I built a system using a new Asus P5Q Deluxe, OCZ ddr2 ram (4meg), dual MSI 8600GTS video and an Intel E6750 processor. I've built all of my own computers over the last 15 years and have never had a problem. In fact, I've only seen one Blue Screen of Death in over 20 systems. I've been using Vista Ultimate. I'm not a gamer. But I work from home and have multiple programs open all the time. Excel 2007, Quickbooks 08, Outlook, Firefox, etc. spread across 3 Dell 2408 monitors. So I've been getting multiple BSOD's ever since I built this computer. I thought they went away when I used Asus's power management and turned the performance down. But it's back. So I figured what the hey and loaded Windows 7. Love it. Same problem. BSOD. Randomly. Then I loaded Windows XP pro. Same thing. I'm using a good heatsink, my power supply is a good one. I always buy the highest rated/most bought parts from New Egg. Anyone have any idea? Could it be my CPU. Why I ask is before this system, I had put the processor in an ABIT board and couldn't load the OS no matter what I tried. Turned out, not understanding the new pin system, I had bent a couple of pins in the CPU socket. So I ditched the ABIT and bought the Asus. Funny though, under a jewelers loupe, I straightened the pins on the Abit, threw in a low end Core 2 and it's been humming away 24/7 as a WHS for 3 months now without a problem. So did I short my CPU? How do I tell.
